Mistakes needs to avoid before submitting the documents for PR

Thanks for the detailing. I appriciate it. One more question come into my mind , hope you don’t mind.
Should I need to submit my birthcertificate? If yes, is it part of miscellaneous field?

The birth certificate is an identification document, you need to attach it. It is one of the most requested ADR (additional document) IRCC asks for.
